All of them already available at https://mk90.pdp-11.ru/library.htm

There are also some reverse-engineered schemes for MK92 rev. 2. MK90 doesn’t control steppers manually, but communicates with KA1835VG6 controller, used to operate embedded ROM, tape system and plotter system. And someone found and scanned a datasheet for it: http://www.155la3.ru/datafiles/ka1835vg6.djvu

There are status and command registers. Plotter is controlled using a set of 18 commands. So I think there must be places where MK90 sends these commands to the command register (and maybe checks status bits).

Another P.S.: Some days ago I tested an emulation of MK85 and found some bugs here. But I think this is a subject of an E-Mail letter.

Could you post all those manual in russian on your Github ? I am currently working on the MK-92 emulation and it would be of great help.

About manual: two months ago I discovered several OCR mistakes in the BASIC listings (bad quality of paper source and small letters, well) and a number of mistakes in the translated version, so I published version 1.51.
Latest (english) version always available at: https://github.com/Bs0Dd/MK90-projs/blob/master/MANUAL/mk90eman.pdf
I also wanted to retype other manuals for MK90 (BASIC programming manual, BASIC 2.0 manual, manuals for MK92 rev. 1 and rev. 2), but currently I have no enough free time to do this.

P.S.: there are troubles with my website now, so it’s offline for 2 months, but I’m working to put it back until new year.
